Premium Bi-Fold Doors

Our bespoke bi-folding doors are custom made to the highest standards and designed to withstand the worst that mother nature can throw at them.

Manufactured from slim-line, thermally efficient aluminium profile (which is strong yet lightweight in construction) and fitted with stainless steel quad rollers – our bi-folds are simple and effortless to operate. Powder coated aluminium is also much less vulnerable to climatic variations which can cause timber or PVCU bi-folding doors to expand and contract – often rendering them inoperable.

We can specify odd or even number configurations without an external handle. This keeps external frame and glass lines clean and continuous as well as improving weather protection.

Our Bi-Folding doors can be manufactured with up to 7 panels folding and sliding to the left or right – providing you with a breath-taking, uninterrupted connection between internal and external spaces. Any odd number configuration will provide a single-access traffic door for day to day use – this can be fitted with multi-point, entrance door style locking or with a simple shoot-bolt operated handle to the inside.

Additional Matching Door-sets: For project continuity we can manufacture single entrance or French doors from our bi-fold profile – this will provide you with matching sight lines which are also slimmer than our standard entrance door system. Single doors can be fitted with multi-point entrance door style locking or with a simple shoot-bolt operated handle to the inside.
